I ohm tested my GPs yesterday and i got some interesting results. Im getting ~2.2 for all of them except GP #6 im getting ~1.8. What do those numbers mean? I thought they were supposed to be all at ~1.0 ohms. It doesnt seem likely that they all are going bad at the exact same rate at the exact same time other than cylinder 6 or could i have used the multimeter wrong?

Sounds like you are correctly measuring. It does seem odd though. I know my "cheap" multimeter will not zero even with leads shorted (it will read about 1.2 ohms, where my Fluke will. How many miles are on your GPs? Cheers!

Well i talked to the electric guy at work and he said you gotta subtract the ohms that the leads read touched together from the reading you get from testing so when i do that i get .9 ohms so well in spec but the 1.8 on cylinder 6 is .5 so that one may need replaced some time in the near future.

As for miles i havent the slightest truck has between 190000-250000 miles(odometer replaced by POs PO so how reliable that is is relative) so it honestly could still be the same ones from factory because the VCs look pretty undisturbed.
